摘要
介绍了金属疲劳损伤的研究历程,概述了金属疲劳中几种典型的本构方程的特点及其应用现状,并分析了影响本构方程的因素,指出如何修正受诸多影响下的本构方程,是研究金属疲劳损伤的难点之一。
The research status of metal fatigue damage is introduced, the characteristics and applications of several typical constitutive equations of metal fatigue are summarized, and the factors which influence the constitutive equation are discussed. It illustrates how to modify constitutive e- quation with various influences is one of difficulties for studying the mental fatigue damage.
